I was given an SKS for Christmas a couple of years ago and I've never fired it.Iit seems like it would be a good gun to have if the SHTF, so I've been thinking about buying a case of ammo for it. I see a lot of deals on ammo in different catalogs. Some of it is steel cased, some from Europe or Asia, and I'm not sure which would be good to get. I don't intend to reload the brass, so that's not an issue. Any suggestions?
